- the extent to which a fluid resists a tendency to flow
- Also calledabsolute viscosity a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared η See also kinematic viscosity specific viscosity
viscosity
/ vĭ-skŏs′ĭ-tē /
- The resistance of a substance to flow. For example, water has a lower viscosity than molasses and flows more easily. Viscosity is related to the concept of shear force ; it can be understood as the effect of different layers of the fluid exerting shearing force on each other, or on other surfaces, as they move against each other. Viscosity lies behind the skin friction component of drag.
- ◆ Kinematic viscosity is a measure of the rate at which momentum is transferred through a fluid. It is measured in stokes .
- ◆ Dynamic viscosity is a measure of the ratio of the stress on a region of a fluid to the rate of change of strain it undergoes. It is equal to the kinematic viscosity times the density of the fluid. It is measured in pascal-seconds or poises .
